SunFire V890 error -256 when boot

UNIX Solaris
1

Hi all!

I've a machine - SunFire V890, it've been failed by OS error for 2 weeks ago, and now, I must reinstall OS (Solaris 10 2009), the progress was successful, but when I reboot, it displayed the error like :

Error -256: Last trap memory ... access aligned
Error -256: Last trap memory Fast Data Access MMU Miss

Evaluating:
Error -256
Stack Underflow
{ok}

I've not ever seen this error like that, and I do not understand how to fix this problem. May you suggest to me to solve it?

Thank you!
